VALIDATING RENOVATION PHASING SCHEDULES USING 4D MODEL BASED METHODS

Scheduling major renovation work in an occupied building represents a major challenge to project managers. Multiple stakeholder requirements from the owner, building occupants, and renovation crews must all be satisfied within a tightly constrained physical environment. This paper describes a renovation planning framework and prototype system that enables project managers to explicitly define and automatically check renovation requirements. The framework is based on and extends 4D model based methods. A case study is presented to show how the framework was used to analyze and compare renovation phasing schedules on a building renovation project. The results indicate that the framework enables better identification of scheduling issues and alternatives.
